JOHN WATERHQUSE, OF NEW YORK, N. Y.

DRIER AND SEPARATOR.

SPECI FIGATIONforming part of Letters Patent No. 790,605, dated May 23, 1905. application filed October 22,1904. Serial No 229,580.

To all whom it may concern.-

Be it known that I, JOHN WATERHOUSE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Drier and Separator, of which the following is a full,

- carrying away the sand and dust contained in the material operated on.

I will describe a drier and separator embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate cor-responding parts in both. the figures.

Figure 1 is a side elevation of a drier and separator embodying my invention, and Fig. 2 is a sectional elevation of the separatingcylinder.

Referring to the drawings, 1 designates an air-compressor operated in any suitable manner. I havehere shown it, however, as having connection with a boiler 2. The compressor forces air into a receiving-tank 3, provided with an interior cooler, here shown as a coiled pipe 4, through which water is designed to flow, whereby the moisture that may be contained in the air is precipitated and collected at the bottom of the receiver, from which it may be drawn as required through a discharge-cock 5. A pipe 6 leads from the receiver'toa jacket 7, surrounding a reheatingstove 8, and this pipe 6 is provided with a controlling-valve 9. From the heater the hot air passes through a pipe 10 into the upper portion of a separator-casing 11, this main pipe 10 being provided with a controllingvalve 12, and from this main pipe 10 a branch 13 leads into the lower portion of the separator 11. This branch pipe 13 is of a smaller bore than the pipe 10, and it is provided with a controlling-valve 14. The separator 11 is of the usual ovate form, with the smaller end downward. it is to be understood, however, that I do not confine the invention to the particular shape shown, as other forms may be employed, provided they are downwardly converging at the lower portion. The separator is supported on a suitable frame 15,and for convenience in manufacture it will be made in' two horizontally-separated sections bolted together. The matter to be operated upon, after being screened into various sizes suitable to the separator, is shoveled from the platform 16 into the separator through the doorway 17, provided with a-door 18, which is held tightly in place by means of screw-bolts 19 and sealed by a gasket 20 of rubber or the like. The heated air is allowed to pass into the separator under pressure through the pipes 10 and 13 at a downward incline, so that while the blasts are suflicient to keep the material under suitable agitation for drying and separation the said material will not be wholly forced out of the casing, as would be the case with direct lateral or upward currents. The air through the pipe 13 enters at the bottom of the separator, where the area is contracted, and passes upward and through the matter, agitating it and absorbing the moisture until sufliciently dry, when the fine particles will pass off as dust through the exit-pipe 21, leading at adownward angle from the upper portion of the separator. The

specific gravity of quartz is 2.7, while that of sure of air, probably not exceeding ten pounds per square inch, coarse sand may be blown away, leaving gravel-stone in the bottom of the separator, which may be taken out through the opening 24 and examined for gem stones. 1

Should the blast be so strong as to carry over gold, it may be detected by the gold dropping into the pocket or trap 26, which consists of a glass tube 27, placed in a metal tube opening from and communicating with the pipe 21, the metal tube being provided at its sides with openings, so that the material in the glass tube may be readily observed and the blast regulated accordingly. The tube 26 is provided with a screw-cap 28 at its lower end, the removal of which will permit the material to flow into a receptacle placed under it.

The separator is provided at its opposite sides with glass-covered bulls-eyes 29, and it is also provided with a glass-covered bullseye 30 at the frontabove the door 18, and through these bulls-eyes the action of the compressed air on the material may be observed, so that the pressure of air may be regulated to suit. While a moderate blast is passing into the bottom of the separator through the pipe 13, a stronger blast may be allowed to pass through the larger pipe 10 for blowing off sand. The screw-cap 25 is provided at its inner side with a plug 31', which practically fills the opening 24, thus preventing it forming a pocket.

Should there be water sufficient for the purpose, it may be used instead of compressed air, and rifl'le-pans may, if found necessary, be placed under the outlet-pipe. If there is no water, as on the arid planes of Arizona, where the air and sand are dry, a heater will not be required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. Adrier and separator comprising a downwardly-converging casing, a main pipe leading into said casing, a branch pipe leading from the main pipe into the casing below the outlet end of the main pipe, the said casing having an outlet at the bottom for the material to be saved, and a discharge-pipe leading from the upper portion the said two pipes being arranged to direct the separating agent into the casing at a downward angle.

2. Adrier and separator comprising adownwardly-converging casing having two outlets at the bottom, one being larger than the other, closures for said outlets, a main pipe leading into the casing, a branch pipe leading from the main pipe into the lower portion of the casing, the said branch pipe being of smaller diameter than the main pipe, and a dust-discharge pipe leading from the upper portion of the casing.

3. In a drier and separator, a downwardlyconverging casing, means for conducting air under pressure into said casing at two points one above the other, a dust-discharge pipe leading at a downward incline from the upper portion of the casing, and a sight-tube depending from said pipe.

4. In a drier and separator, a downwardlyconverging casing, means for conducting air under pressure into said casing at two points one above the other, a discharge-pipe leading from the upper portion of the casing at a downward incline, a metal tube depending from said discharge-pipe and having side openings, and a transparent tube arranged in said metal tube.

5. Adrier and separator comprisingadownwardly-converging casing having a small discharge portion at its lower end and a larger discharge-opening at its lower end, closingcaps for said openings, a block on the inner side of the cap for the larger opening, and means for directing air under pressure into the casing.

6. A drier and separator comprising a downwardly-converging casing having outlets at the lower end and a discharge-pipe leading from the upper portion, glass-covered bullseyes arranged in the wall of said casing, a door for an opening in the casing, a gasket arranged around the door, and means for (lirecting air under pressure into said casing at two points, one above the other and under different pressures.

7 A drier and separator comprising a downwardly-converging casing, a compressor, an air-receiver having communication with the compressor, a main pipe leading from the airreceiver into the said casing, and a branch leading from the main pipe into said casing, the said branch being of less diameter than the main pipe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN WATERHOUSE.
